SASH-PIVOT CONSTRUCTION.

Specification of Letters Patent.

PatentdFebJS, 1916.

Application filed November 19, 1913. Serial No. 801,774.

To all whom it may concern: 7

- Be it known that I, HARRY W. CRANE, a citizen of the United States, residing at Philadelphia, county, of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement 'in Sash-Pivot Construction, of which 1 the following is a being had to the accompanying drawings, which form a part of this specification.

My invention relatesto windows, and particularly to that class in which counterbalanced sashes, in addition to having 'a vertical movement in a window frame, are

capable of swinging on a horizontal axis midway between the upper and lower ends. Such a window is set forth in the patent to George, No. 776,177, dated November 29th, 1904.

The object of my invention is to improve the construction of the window of that patcut and more particularly to provide improved means for pivotally mounting the sash upon the supplemental stile or shoe. 'and for holding the sash in any position certain parts of the pivotal connection removed. Fig. 3 is an inside face view of the shoe. Fig. 4 is an inside face view of the sash. Fig. 5 isa longitudinal section through the central part of the shoe and sash. Fig. 6 is a section on the line-;6- 6-of Fig. 5.v Fig. 7 isa section on the line 7-7 of lFig. 5.

full, clear, and exact description, reference.

.fit into the recess 7. plate 1' is T-shaped.

7 0; indicates the window framethe same being provided with the three vertical parting-beads b, b, b, forming two grooves or run-ways c, c, in which slide the stiles of the two sashes. In the drawings I have,

for convenience, shown only lower'sash w as pivoted on'a slidingshoe, the upper sash (Z being unprovided with a-special shoe and being similar to the upper sashof an ordinary double-hung window; but it will be understood that my invention may 'beapplied to either or both sashes. of the two grooves 0 is a slidable'shoe e, which is of substantially the length of-the sash which it sustains and is of a thickness somewhat greater than the depth of the groove in which it slides. About midway betweenthe ends of the shoe the same is cut away between its front and rear faces to form a recess. 7. The edges of the shoe ad- In the inner 1 V jacent to the facefthereof opposing the sash are rabbeted, as at g. The edges of the sash shoe are similarlyrabbeted as at 7L.

A plate 2' extending from the upper to the The plate iso-ffset at its'central portion to At oppositeends the At one end, say the vupper end, of the plated, the head of the T is at the outside of the shoe, one angle thereof extending into the outsiderabbet of the shoe and the other angle extending, when'the sash is closed, into the outside rabbet of thesash. At the other end, say the lower end, of the plate 2', the T is at the inside ofthe shoe, one angle the head of thereof extending into the inside. rabbet of the shoe and the other angle extending, when v the sash is closed, into the inside rabbet of the sash. ,Each T-head of the plate 6 .6Xten'dsfr'o'm one endof the shoe toward .the pivot of the sash but does, not extend as far as thepivot.

w adjacent tothe face thereof opposing the A plate 9';- extending from the upperto V the lower end of the sash, is applied and secured to the face of the sash opposing the shoe. This plate is also T'shaped at opp0- site ends. At one end, say the upper end, of the plate j, the head of the T is at the inside of the sash, one angle thereof extending into the inside rabbet of the sash and the other angle extending, when the sash is closed, into the inside rabbet of the shoe. At the other end, say the lower end, of the plate 7', the head of the T is at the outside of the sash, one angle thereof extending into the outside rabbet of the sash and the other,

end extending, when the sash is closed, into the outside rabbet of the shoe. Each T head of the plate j extends from one end of the sash toward the pivot thereof and beyond said pivot to such a distance that, when the sash is closed its end abuts against the corresponding T-head of the shoe. It will be understood, however, that the relative lengths of the T-heads of shoe and sash may be the reverse of that described. The heads of the T are preferably formed by bending 1 the metal of the plate first in one direction,

then in the other direction and then back again to the leg of the T, thus forming from a single piece of metal a T-shaped plate whose head is of twice the thickness of itsleg.

At the center of the depression f the shoe is formed with a circular orifice extending from the base of the depression, or the face of the shoe opposite the sash, to the face of the shoe sliding in the groove in the frame. Immediately opposite this orifice the sash is provided with a recess Z of similar cross-section. This recess and orifice are adapted to receive the pivot pin or bolt m, the head n of which extends into the recess Z. A collar 0 provides a bearing for the bolt. This collar is provided with a flange which overlaps the recess l, the over lapping edge of the flange being countersunk and secured in the face of. the sash.

The neck of the collar 0 extends within an orifice formed by annular flanges bent toward each other from the plates 2' and j. A filler ring 2 extends between the plates '11 and j and surrounds the inturned flanges thereof.

A cup-shaped spring Washer 79, sleeved on the bolt m, is confined between the plate 71 and two nuts 1', 'r, threaded on-the bolt. The boltim has a neck engaging a slot in a locking plate 8, which is countersunk in the working face of the shoe 6. This holds the bolt from turning. 1

The offset part of the plate 2', or that part thereof which fits into the base of the recess f,'is provided, above and below the pivot, -with vertically extending shallow depressions or pockets a which fit into correspondlng depressions 1n the base of the recess f.

In the space,-with the recess f,between=the plates 2 and j, pivot, 1s a flanged and above and below the holding plate 6 having ridges 0 adapted to the depressions w.

Having now fully described my invention,

what I claim and desire to protect by Letters Patent is 1. A sash pivot construction comprising] two members shaped to form between them 1 an elongated recess and flanged to form an opening for a pivot, a collar within said.

opening, a filler ring surrounding said flanges, tension devices within said recess on opposite sides of the pivot opening tending to maintain said members inthe angular relation into which they are moved, and. a pivot pin extending through the collar.

said members, a pivot bolt extending through said collar, a head on the bolt contacting with the flange of the collar, a nut on said bolt, a spring washer confined by said nut against one of the said members, and tension devices within said recess-on oppositesides of the first opening tending to maintain said members in the angularrelation into which they are moved.

3. A sash pivot construction comprising, two members shaped to form betweenthem an elongated recess, a pivot'pin extending through said recess, abearing surrounding the pin and a filler ring surrounding the bearing, holding plates Within said recess on opposite sides of the filler ring, each In testimony of which invention, I have hereunto set my hand,rat Phi1ade'1phia,7on this 28th day of October, 1913.
